1 EVM Overview
1.1Features
DAC7716EVM:
•Contains all support circuitry needed for the DAC7716
•Voltage reference options: Either 5V or 2.5V onboard, or external
•Jumpers on output pins for gain adjustment
•Compatible with the TI Modular EVM System
This manual covers the operation of the DAC7716EVM. Throughout this document, the abbreviation EVM and the term evaluation module are synonymous with the DAC7716EVM.
1.2Introduction
The DAC7716 uses a
is controlled by the addition of a feedback resistor. An additional VMON pin can relay any of the four output channels from the DAC or the signal from the AIN pin.
The DAC7716EVM is designed to run in either bipolar (default mode) or unipolar modes of operation. This flexible design allows for a wide range of supply voltages. The operating mode can be controlled using an onboard switch or digitally, through the digital header.
The DAC7716EVM is an evaluation module built to the TI Modular EVM System specification. It can be connected to any modular EVM system interface card. The EVM ships in the
Note that the DAC7716EVM has no microprocessor and cannot run software. To connect it to a computer, some type of interface is required.
